The Much Countdown (also known as the Much Top 30 Countdown, and formerly known as The MuchMusic Top 20 Countdown) is an hour-long musical television program, usually hosted by a VJ, that aired on Canadian music television station MuchMusic from 1996 to 2017.^[1][2] Countdown was one of the longest-running programs that has aired on MuchMusic since the channel's debut. Originally sponsored by Coca-Cola, it was known for the first several years as the Coca-Cola Countdown.^[3]

The program aired a playlist of the most well-known songs in the mainstream. The order that the videos were played went from No. 30 to No. 1, although only about 10-12 of those videos were actually played. Most of the videos that went unplayed were older videos that were fading off the charts, or less popular videos. A video that was moving down the chart or was in the same spot as that previous week would in general not get played. Every video debuting on the chart was played. A music video that reached the No. 1 spot usually stayed there for 1–2 weeks.
